Nope. A rough count shows that over twenty million people work directly for our govenments from local to federal.

If we reduced government by 90% by reduction, automation, privatization and outright agency elimination you'd still have two million people in government.
"Ultra-limited" does not mean "no government".
I think 50% to 75% could be a good range. So you'd still have somewhere between five and ten million people in government.
Also, "ultra limited" refers more to what they are allowed to do rather than how many.
